The clinical presentation, radiographic features, and histopathological findings of a case of ameloblastic fibro-odontoma are described. The clinical and radiographic presentations of this case are typical of this benign odontogenic tumor. The patient was young and asymptomatic with the exception of the clinical absence of the permanent mandibular left first molar. Treatment consisted of simple enucleation with removal of the primary mandibular left second molar.
A panoramic image and cone beam computed tomography (CBCT) scan were acquired in order to determine the reason for clinical absence of the permanent mandibular left first molar. The CBCT image proved to be a valuable supplement to the conventional radiographic examination as it provided information not apparent on the 2-dimensional panoramic image. Both the extent of the lesion and its effects on adjacent structures were better delineated with CBCT. Additionally, the presence of calcifications, an important radiographic characteristic of this particular lesion, were visible on CBCT versus the panoramic image.
This case report demonstrates that the CBCT scan provided important management and treatment planning information that was not apparent in the panoramic image.
描述了一例成釉细胞纤维牙瘤的临床表现、影像学特征和组织病理学发现。该病例的临床和影像学表现是这种良性牙源性肿瘤的典型表现。患者年轻且无症状,只是临床检查发现下颌左侧第一恒磨牙缺失。治疗方法为简单摘除肿瘤并拔除下颌左侧第二乳磨牙。
获取全景图像和锥形束计算机断层扫描(CBCT)以确定下颌左侧第一恒磨牙临床缺失的原因。CBCT图像被证明是对传统影像学检查的有价值补充,因为它提供了二维全景图像上不明显的信息。CBCT能更好地描绘病变范围及其对相邻结构的影响。此外,钙化的存在作为该特定病变的重要影像学特征,在CBCT上比全景图像上更易观察到。
本病例报告表明,CBCT扫描提供了全景图像中不明显的重要管理和治疗计划信息。
